Time to level up your high-feed milling operations with the best-in-class CoroMill® MH20. Engineered for versatility, the CoroMill MH20 is optimized for pocketing applications in ISO S, M, and P materials while covering a wide range of machining tasks. With a light-cutting geometry and robust shank design, it delivers secure, vibration-free performance—even in long-overhang applications.

The Steiner Metalworking application team is here to help. We’ll assist you in selecting the ideal high-feed milling tools for your operation and provide expert guidance on process improvements to boost productivity, reduce costs, and extend tool life.

Robust Cutter Body

The cutter body material offers higher fatigue and deformation resistance, ensuring longer tool life. Combined with a robust shank design and light-cutting action, CoroMill® MH20 ensures secure, vibration-free machining—even at extended overhangs.

Open Insert Pocket

The open pocket design improves chip evacuation and reduces re-cutting. Optimized for high-feed machining, this feature is especially beneficial in ISO S applications by minimizing chip smearing and improving overall process security.

Curved Insert Design

The single-sided, two-edged positive insert features a curved edge and reinforced corner radius. This provides secure, stable performance during pocketing, especially against walls and corners, enhancing both tool life and surface quality.

Features & Benefits

  • High-feed design supports multiple operations, reducing tooling needs and cycle time.
